Causes
Communication data format
(start code) is inadequate.
Communication data format
(end code) is inadequate.
Command mode (LP-400/V
compatibility setting) is wrong.
An error occurs.
Marking trigger is in
progress.
Laser pumping is turned
OFF.
Internal shutter is closed.
File switching is not
complete.
Either of registered
characters via I/O, external
offset or characters specified
by SIN command are used
and marking data is not input
from the external control
device.
• For RS-232C or Ethernet, check if the start code specified
in laser marker system settings screen and start code of the
transmitted data are consistent.
• If you use EtherNet/IP or PROFINET, do not contain the start
code in the command data.
• For RS-232C or Ethernet, check if an end code is placed at
the end of the transmitted data.
• For RS-232C, check if the end code is the value specified in
the laser marker system settings screen.
• If you use EtherNet/IP or PROFINET, do not contain the end
code in the command data.
• If you want to use the same command format with the
former models of LP-400/LP-V series, enable "LP-400/V
compatibility" in system settings of Laser Marker NAVI smart.
• If you want to use the standard command format, switch the
mode by RSM command or disable "LP-400/V compatibility"
in system settings of Laser Marker NAVI smart.
• If you use EtherNet/IP or PROFINET, deactivate "LP-400/
V compatibility" in System settings screen. You cannot use
the command format in LP-400/V compatible mode via
EtherNet/IP or PROFINET.
Check the error code and cancel the alarm or warning.
• Do not input the next marking trigger until the trigger
processing is completed.
• When trigger mode is set to Multiple triggers at on-the-fly
marking, max. 16 triggers can be accepted while the trigger
processing operation.
Turn ON the laser pumping.
If the laser pumping fails, refer to "Laser pumping" in
Troubleshooting.
• Open the internal shutter.
• Check if the shutter open/close control method set in the
system settings screen (I/O or communication command) and
the actual control method are consistent.
• If the shutter open/close method is changed in the system
settings screen, restart the laser marker.
If the file number is changed, the marking ready is turned OFF
for dozens of ms or seconds to create marking data. Input
marking trigger signal after making sure that READY output is
ON if you changed the file.
• If "Registered characters via I/O", "External offset" or
"Characters specified by SIN command" are used, input
respective data at every marking.
• For LP-RC/LP-RF/LP-RV series:
Using DATA WAIT OUT (No.38) of I/O connector, you can
confirm the laser marker becomes waiting status of input.
